## Description

ComStar Pure Lye is an industrial-strength environmentally safe, bead formula designed to clear out drains, grease traps, septic systems, and roots. ComStar Pure Lye is also a best-selling soap maker. This sodium hydroxide formula is the purest white, bead-size lye in the world—99% pure. A natural drain opener, ComStar Pure Lye is biodegradable and odorless with a non-acid formula that is safe on fine fixtures, chrome trim, and metal or plastic pipes. This amazing product clears out clogged and slow-moving drains, grease traps, and septic systems, without harming septic tanks or cesspools. Because of the unique bead shape, ComStar Pure Lye will sink to the bottom of standing water and attack the cause of the blockage for a fast break-up. ComStar Pure Lye does not stink or create fumes and has become a favorite drain-opening product for homes, schools, hospitals, cafeterias, and restaurants. ComStar Pure Lye’s small bead form is preferred for soap making. Unlike more common flake formulas, ComStar Pure Lye Beads do not clump together, create static, and dissolve quickly. Because of this, soap making is faster and easier with ComStar Pure Lye.

Review: It will clear your drain - I have four bathroom vanities, one kitchen sink (open drian and garbage disposal sides) as well as a utility sink. In addition to multiple shower drains, a soaker tub drain and a jetted garden tub drain. It's easy to see that with all of these drains, something will eventually need your attention. Sink drains provide relatively easy access to the trap and with a modest amount of effort they can be cleaned out manually. If however the clogg goes far beyond the trap the repair gets a little more intense. Of course shower and tub drains typically don't have easy access to their drain plumbing. This is the answer for these scenarios. Not only will it open up the drains, it will do so quickly and as an added benefit it will help to keep things downstream from clogging in the first place. I have also found that it works well in laundry drains where soap scum and fabric softener buildup can become problematic. It can be used preventatively in utility drains such as HVAC A Coil condensate drains. Who wants to find their AC system shutting down because the condensate tray is backing up? Or worse yet, find out that the system didn't shut down but instead overflowed onto your carpet, hardwood or even worse, into your ceiling if the unit is upstairs or attic located. This stuff works well for opening clogged drains quickly and preventing clogs when used as a maintenance aid. I typically by this in either the large container or in two packs as I want to have it on hand when needed. I also restock quickly when low.
Review: AMAZING PRODUCT!! WELL WORTH THE PRICE!! - I was amazed how this product worked on my slow moving bathtub/shower drain! I had tried snaking it, plunging it, liquid drain cleaner...nothing helped until this. I watched the videos people posted and thought what the heck, I'll give it a try. Ran hot water for a minute, waited 10 minutes, poured 1/4 cup directly into the drain, added more hot water, saw 1 bubble (burp) waited, repeat ran hot water 1 minute, 10 minutes later added the beads, little more hot water...finally drain opened up completely. Will use as a monthly maintenance to keep functioning.

### ⭐⭐⭐⭐⭐ It will clear your drain

### ⭐⭐⭐⭐⭐ AMAZING PRODUCT!! WELL WORTH THE PRICE!!
*by S***A on January 7, 2026*

I was amazed how this product worked on my slow moving bathtub/shower drain! I had tried snaking it, plunging it, liquid drain cleaner...nothing helped until this. I watched the videos people posted and thought what the heck, I'll give it a try. Ran hot water for a minute, waited 10 minutes, poured 1/4 cup directly into the drain, added more hot water, saw 1 bubble (burp) waited, repeat ran hot water 1 minute, 10 minutes later added the beads, little more hot water...finally drain opened up completely. Will use as a monthly maintenance to keep functioning.

### ⭐⭐⭐⭐⭐ It works! Used whole bottle, exact steps I took below
*by R***3 on May 10, 2016*

This stuff really works! I had a really bad clog in my kitchen sink and I'm on septic and since this is safe for septic tanks (except MA due to state law) I figured I'd give this a go before asking my SO to snake the drain since that's such a messy job. I ended up using the whole bottle to clear the drain. The clog was so bad that it literally took ~6-8 hours to drain the sink. The bottle comes with ~2 cups of beads. You use 1 cup per application so if you only have to use 1 cup to clear, you'll have enough left over for a future clog. See below for exact steps I took. The first cup, I followed the directions almost exactly: waited for the sink to be empty, poured 1 cup of beads down the drain, boiled ~3 cups of water and poured all of it down to dissolve the beads, heard a growling sound for a few secs, waited ~5 minutes then ran hot tap water to see if the drain was clear... it wasn't and didn't seem to make a difference at all. So I did a little research on the net and found that you should let the pipes empty as much as you can down to the clog or the lye can become too diluted by the time it reaches whatever is causing the clog. So with the second attempt, I didn't use the kitchen sink all evening and let the pipes fully empty overnight. Then first thing in the morning I poured the rest of the bottle down the drain, boiled water again but this time I only used ~1/2 cup to dissolve the beads. I poured just enough water until the beads were dissolved and the "growling" sound started. The sound went on for a bit longer than the first time I used it and it seemed to "fall" away from me as it went down the pipe. I then left it for ~2 hours. I then boiled ~3 cups of water and poured it down the drain. Again, I heard the growling sound and assumed it was still working on the clog so I left it for ~15 minutes. Again, I boiled ~3 cups of water, poured, growling sound, left alone for ~15 mins. I repeated this process (boil ~3 cups, pour, left alone ~15 mins) until the growling sound stopped (maybe 4 or 5 times). I then ran hot tap water and it looked like it worked but then both sinks filled slightly above the drain. I turned off the tap and about 20 secs later, the drains bubbled a bit then emptied as expected. I then ran hot tap water for ~3 mins and no more clog. The sink drains like a champ now! I will be ordering more of this stuff so I have some on hand for the next clog. Highly recommend.
